The invention relates to a construction system using multi-layer precast concrete elements, combining vertical elements (FIG. 1) and horizontal elements. The vertical elements are formed by precast panels containing the following layers: outer or facade layer (1), an insulating layer (2), a structural concrete layer (3) and internal finishing layer (6). Horizontal elements include a layer of structural concrete.

A multi-sided structure, constructed from a plurality of prefabricated components consisting of fewer than 12 different prefabricated structural components, includes a floor assembly; a roof assembly; and a side assembly connected to the floor assembly and the roof assembly and extending between the floor assembly and the roof assembly. The floor assembly includes a plurality of the floor panels, each floor panel in direct structural connection with at least one other floor panel. The roof assembly includes a plurality of the roof panels, each roof panel in direct structural connection at least one other roof panel. The side assembly includes a plurality of the wall panels, each wall panel in direct structural connection with at least one floor panel and at least one roof panel.

A prefabricated demising wall assembly comprising two substrate panels each with an interior and exterior surface, the substrate panels configured to span between a floor and a ceiling of a building unit; a plurality of metal studs connecting the interior surfaces of the two substrate panels, wherein the plurality of metal studs define a space between the substrate panels; a fire sprinkler pipeline between the two substrate panels, wherein at least some of the plurality of metal studs have an aperture accommodating the fire sprinkler pipeline through an interior of the demising wall assembly; and a plurality of hanger elements operably attached to the exterior surfaces of the two substrate panels, wherein the plurality of hanger elements are configured to connect to a plurality of removable finish panels.

A modular unit including a concrete pad and a base support affixed to the pad. An anchor collar affixed to the base support and defining spaced apart grooves with a multi-arm beam positioned in the collar, one arm in each of the grooves and extending radially outwardly from the collar. Floor sections affixed to the multi-arm beam to form a floor disc. Wall panels affixed to the floor disc and spaced apart around the periphery to define a wall. Each panel having channeled edges. A plurality of window inserts engaged in opposed channeled edges of adjacent wall panels. A retaining ring extending around the wall and having a downwardly opening groove engaged with an upper edge of each window insert and fixedly attached to an upper edge of each of the wall panels. A roof and roof support structure affixed to the roof.

A building system may include at least one diaphragm beam having opposite ends connected to an external structural frame of a building, at least one pre-assembled floor-ceiling panel adjacent to a vertical side of and coupled to the diaphragm beam, and at least one pre-assembled wall adjacent to a horizontal side of and coupled to the diaphragm beam. The diaphragm beam may be filled with a mineral-based material, such as concrete. The one or more pre-assembled floor-ceiling panels may each include a plurality of joists extending perpendicular to the diaphragm beam, a floor-panel including at least one metal layer attached to the joists on a floor side of the pre-assembled floor-ceiling panel, and a ceiling panel including at least one layer comprising mineral-based material attached to the joists on a ceiling side of the pre-assembled floor-ceiling panel. The one or more pre-assembled walls may include interior and/or exterior walls of a building.

A retrofitting appliqu for stepped application to a building wall construction. For external retrofitting, the system has an air barrier layer impermeable or semi-permeable for moisture, a ventilated air cavity used to modify temperature and/or remove water that may be coming from both sides or to modify the relative humidity of the ventilation air, a layer of thermal insulation, a composite material called Eco-Wrap with capillary active capability, in which a hydronic heating or cooling system may be located, and a surface finishing layer. For internal retrofitting, the system has an air barrier system arranged onto the wall of the building and separated from a layer of permeable or semi-permeable thermal insulation by a ventilated air gap. The layer of insulation, in turn, is in contact with a layer of Eco-Wrap. A permeable interior finishing layer that may also have capillary active performance is in contact with the Eco-Wrap. Methods for installing the retrofitting appliqu are also disclosed.

A building component utilizing a pourable polyurethane or structural foam that can be used for floors, walls, and roof assemblies with a frame with an interior, back or a front, multiple partition beams forming cells in said frame, pourable polyurethane or structural foam exterior backing attached to said frame back. The structural foam is poured into said cells to a desired level, and after said structural foam is poured into said cells, said interior backing is attached to said frame front. Cabling is used to improve movability of the invention, and improve on wind loading and seismic requirements of the present invention. Safety is also improved during the manufacturing process, loading, unloading, and in final assembly through the use of cabling.

An environmental system is disclosed. The environmental system is configured to provide varying degrees of ventilation and shading. In addition, the environmental system can include provisions for collecting rainwater and holding greenery. The system can includes a mounting structure, a set of frames, a plurality of bars, skins, beams, and optionally one or more plants.

The present invention provides a method for framing a building structure prefabricated with electrical wiring, plumbing, and HVAC system, the method comprising: designing interior functions of each floor within the building structure; determining the positions of the electrical column, the plumbing column, the HVAC column, the electrical beams, the plumbing beams, and the HVAC beams in the building structure based on the interior design of the previous step, and these positions also comply with a location selection principle; installing the electrical column, the plumbing column, the HVAC column, the electrical beams, the plumbing beams and the HVAC beams; and connecting the electrical wires on the electrical columns and the electrical beams, the water pipes on the plumbing column and the plumbing beams, and the ventilation spaces in the HVAC column and the HVAC beams. Through above-mentioned method, the present invention is intended to realize rapid house building process with safety.
